King James Version
And it shall be Aaron's and his sons' by a statute for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifice of their peace offerings, even their heave offering unto the LORD.English Standard Version
It shall be for Aaron and his sons as a perpetual due from the people of Israel, for it is a contribution. It shall be a contribution from the people of Israel from their peace offerings, their contribution to the LORD.New International Version
This is always to be the regular share from the Israelites for Aaron and his sons. It is the contribution the Israelites are to make to the LORD from their fellowship offerings.
